IMPROVEMENT IN WHIFFLETREE-IRONS.

Specification forming part of Letters Patent No. 210,554, dated December3, 1878; application filed November l, 1878.

To all whom t may concern:

Be it known that I, CHARLES H. PALMER,

J r., of Merrimac, county of Essex, State ot'Massachusetts, haveinvented an Improvement in Wlliftletreeflrons, ot' which the followingdescription, in connection with the accompanying drawings, is aspecitication.

This invention relates to devices chiefly applicable to hold awhifiietree-bar upon its cross-bar, either of shafts or poles; but thedevices, made of proper size, may be used as the connecting meansbetween other portions of carriages or things one otl which is tooscillate upon another.

The object of my invention is to form a practically noiseless,water-tight, and firm connection between the whitetree and itscross-bar; and my invention consists in a flanged plate or washeradapted to receive within it an an nular disk, about which the flangedplate oscillates, the disk and plate being held together by a bolt, thehead and nut of which are conccaled.

Figure l represents an inverted partiallysectional view oi a piece of awhiftletree-bar and a cross-bar, held together by my improved devices,and Fig. 2 is a top view of Fig. l.

In the drawing, a denotes part ot` a crossbar, and b part ot' awhiftletree-bar, of a carriage. The connecting' devices are shown ascomposed of a plate, c, having about it an annular Bange, 2, preferablyof a sufcient depth to receive within it a disk, d, and extend beyondthe outer face of the disk, so as to bear against the wood-work of thecross-bar, as shown in Fig. l. This annular plate is attached to theWhipetree by two rivets or bol ts, e e, extended through both. rIhe diskd is secured to the cross-bar by means otl bolts j' f, provided withnuts g, to permit the whiiietree to be detached.

llhe plate and disk are held together by a bolt, h, the head and nut ofwhich are let into recesses in the whiflietree and cross-bar, and arealways retained out ot' sight, and the connection is such that the nutcan never become detached from the bolt 7L.

Wlhen putting the parts together, the bolt his irst passed through theopening at the center of the plate c, the plate is placed again st theunder side of the whittletree, with the head ot' bolt h in a recesstherein, and the rivets ce are inserted. The bolts f f are then insertedthrough proper holes in the disk, the disk has its central hub placeddown over the bolt It and into the opening at the center oi' the plate,and the nut is applied to the bolt h and turned to make the joint asclose as desired. Then the bolts f, projecting from the disk d and thewhiftletree, arc inserted through holes in the cross-bar a, the nut otbolt 7L is received in a recess in the cross-bar, and the nuts g g areapplied.

The iian ge2, meeting and tting against the cross-bar closely, as shownin Fig. 1, excludes water and dust.

Preferably, the anged portion of the plate will be painted the saine asthe whiflietree, thereby practically concealing the iron-work at thepoint where the whiii'letree turns.

A packing may be used between the tlange 2 and cross-bar.

I claiml. The bars a b, colnbined with the plate provided with acircular tlange, the disk withvin it, and the connecting-bolt h, thehead and nut of which are concealed in recesses in the said bars,substantially as described.

2. A whittletree and cross-bar connecting device composed of a diskadapted to be attached to the crossbar, a plate provided with a circularflange adapted to be connected with the whiiiietree, to surround orinclose the disk and form a water-tight joint at the cross-bar, and acentral bolt, h, the said disk and plate being provided with openingsfor the reception of bolts and rivets, substantially as shown anddescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribin g witnesses.
